蚂蚁：文件集＆QUOT; DIR＆QUOT;有一个运行时扩大完整路径属性 [英] Ant: fileset "dir" attribute with a runtime expanded full path

问题描述

让我们说我有一个文件系统，看起来有点像这样：

Let's say I have a file-system that looks a little something like this:

• C：\\东西\\ build.xml文件


• C：\\东西\\ MyFolder文件\\ library1.jar


• C：\\东西\\ MyFolder文件\\ library2.jar

里面的build.xml，我想定义看起来像这样的路径：

Inside build.xml, I want to define a path that looks like this:

<path id="some.id">
    <fileset dir="myfolder">
        <include name="**/*.jar"/>
    </fileset>
</path>

通常工作正常。不过，我打电话给我自己的自定义Ant任务将继承任何引用（包括路径some.id）和自定义的Ant任务将调用，生活在不同BASEDIR一个build.xml。因此，目录属性的文件集不再有效。

Normally that works fine. However, I am calling my own custom Ant Task that will inherit any references (including the path "some.id") and that custom Ant Task will call a build.xml that lives in a different basedir. Therefore, the "dir" attribute in the fileset is no longer valid.

有没有办法定义一个目录，使得它仍然有效无论身在何处第二的build.xml生活？

Is there a way to define a "dir" such that it remains valid no matter where the second build.xml lives?

基本上我想要做这样的事情：

I essentially want to do something like this:

<fileset dir="${expand.current.directory}/myfolder">

所以，当我打电话第​​二的build.xml会明白，目录属性的位置：

So when I call the second build.xml it will understand that the "dir" attribute is the location of:

<fileset dir="c:\stuff\myfolder">

编辑：此外，我想一个解决方案，可以让我的东西项目从一台计算机复制到另一台，而无需更改构建。例如，如果东西项目是在C：盘，我在复制该项目到D：驱动器另一台机器上，我要构建继续没有我不必去到构建和改变信合作C到字母D。

Furthermore, I want a solution that allows me to copy the "stuff" project from one machine to another without requiring a change to the build. For example, if the "stuff" project is on the C: drive and I copy the project over to a D: drive on another machine, I want the build to continue to work without me having to go into the build and change the letter C to the letter D.

推荐答案

我觉得你的 $ {user.dir来} 属性之后是 - 这是当前工作。目录

I think you're after the ${user.dir} property - which is the current working directory.

所有的Java System.properties 可作为ant属性。

All java System.properties are available as ant properties.
